März 2010

Hello,
in the use of an external mic with a camcorder strong noises arise when the camcorder is operated with battery but with a power supply.
This is both the Panasonic NV-GS280 alsauch in SonyDCR-HC14E the case.
Can someone help us?
We have used as an external mic, the EM35 of Vineo.
Thank you very much
Henning

Hello,

therefore, some sound engineers synonymous reluctant to allow operation of the network, because it is synonymous may affect other devices (mixer).


However, it should nonetheless be noise filters, plus other users can safely say more. I got me that time after being warned, and limited to the larger noise Batteries.

If they did relate to the background noise to the typical 50-Hz line hum, then the power supply is simply inadequate. That will be very many of these mini-power supplies, which come with the camera in the case. Special power supply units with fully smoothed DC output voltage, however, can go into the money fairly.
Therefore: Batteries only work with large, use special power supplies.
Added, however, is another problem with the mini-jacks: if the supply cable of the mic for more than about 50 cm, then it takes almost synonymous as an antenna for electromagnetic 230V AC voltage of the lead wire is located close to the network device and is then very to hear clearly.
